While this Platinum will take some time, the difficulty lies in the skill required. A very challenging game with some very challenging trophies - particularly if you go at it legitimately. Using the save feature can help, in which you can reload if you mess up a play.

Expect to become quite a master at this game to earn the Platinum.

It's highly recommended that you begin with the tutorials. You can earn a few trophies here, plus it will help you get acquainted with the controls and overall gameplay of this challenging title.

Next, you can start in on the Ashes series. Here is where you can earn the majority of the trophies. You have the option of playing offline or online. If you have a boosting partner and can manage to connect into a ranked match together, this could make things a bit easier. If not, remember you can save your progress - this can help if you start to lose your streak.

Afterwards, besides moping up any trophies you missed in the Ashes series, there are the final tournament trophies to collect.
